.. LATCH FOR CHANGE-SPEED GEARS FOR AUTOMOBILES.

To all whom it may concern:

Be it known that I, EMILE LEON PROSPER Mons, a subject of the King of Belgium, of 48 Rue du Theatre, Paris, France, engineer, have invented a certain new and useful Latch for Change-Speed Gears of Automobiles, of which the following is a full, clear, and exact description.

This invention relates to apparatus for latching or looking the change-s eed and reversing mechanism of automobi e vehicles.

The description is given hereafter with reference to the annexed drawings in which Figure 1 shows the device in longitudinal elevation, art section. Fig. 2 is a cross section upon 'ne 2-2 of Fig. 1. Fig. 3 is a plan view and Fig. 4 is a view, partly in section, of the mechanism as seen from the left of Fig. 1.

A B C indicate three rods (this number might be less or greater) connected to the parts of a change speed and reversing mechanism, for example, two sliding trains and an intermediate reversing. inion. In opera tion one rod receives a ongitudinal movement, the two others being during this time immobilized. These three rods A B C are placed along an arc of a circle concentric with the axis of a spindle D; the latter which is capable of receiving a longitudinal displacement is maintained in a support E and engaged in a sleeve F revolubly mounted thereon between the two parts of this support E. The sleeve F is connected to the spindle D by a long feather so as to partake of its rotation although allowing its longitudinal displacement.

The spindle D carries a tooth d intended to be engaged in the transverse notch of any one of the rods A B C. The sleeve F has a circular collar or rib f which can engage with the notches in the rods and this rib is cut away at one point to form a notch in line with the tooth d.

To the spindle D there can be imparted a longitudinal and rotational displacement by the following contrivance. It carries at its extremity two short arms D connected by a pin (1 on which is mounted at right angles a tube which engages the fork g of an arm G secured to a tubular shaft H, mounted upon a fixed shaft I. The tubular shaft H is at tached to the gear lever shown at h to which an angular movement as well as a transverse Specification of Letters Patent.

displacement may be imparted in the well known manner.

It will be seen that when the lever h is given an angular movement the spindle D receives a longitudinal displacement; fur ther when the former'is given a transverse displacement the spindle and consequently the sleeve F receives an angular movement. The movements of the lever h are determined so that by the rotation of the spindle D the tooth d is brought into the notch of one or other of the rods A B O, and that the longitudinal movements of said rods are those necessary for the engagement of the gear wlgleels or other parts connected to the said ro s.

The working-is as follows :When by the operation of the lever h the spindle D has been brought to the angular position so that its tooth d is engaged in the notch of that one of the rods A B C which is to be 0 erated, the notch in the collar f upon the s eeve F has effected the same movement and consequently permits the displacement of the rod under consideration, while the two others are locked owing to the entrance of the collar f within their notches; the rod in question can then receive its longitudinal movement while the two others are latched; the same applies for each of the rods A B C, and it will be understood that their number might if desired be increased without difliculty.

My invention may be modified in various ways without evading its scope, and I do not limit myself to the particular construction shown.

I claim as my invention:

1. The combination in shifting mechanism of an operating spindle, and a plurality of shifting-rods parallel thereto and actuated thereby, and means for locking the remainder during the movement of one of the rods by said operating spindle.

2. The combination in shifting mechanism of an operating spindle capable of angular and longitudinal motion, a plurality of shifting rods substantially parallel thereto and capable of individual longitudinal displacement thereby and. means for locking the remainder during the movement of one of said shifting rods by said operating spindle.

3. The combination in shifting mechanism of an operating spindle, a plurality of shifting rods actuated by and concentrically arranged around the spindle, and means for locking the remainder during the movement of one of said shifting rods by'the operating spindle,

substantially as described.

4. The combination in shifting mechanism of an operating spindle provided with a tooth, a plurality of shifting rods arranged concentrically around said spindle and provided with transverse notches adaptedztozoooperate with said tooth, and means for locking the remainder :during the movement of one -0 said rods by the spindle.

5. Thecombination in shifting mechanism of an operating spindle (provided witha tooth and capable of angular .and longitudinal motion, a sleeve on said spindle and secured the tooth-on the spind e, and a plurality of shifting rods capable of longitudinal movement with the spindle and provided with notches adapted to be engaged bysaid rib and tooth, substantially as described.

In testimony whereof I have signed my name to this specification, in the ,presenceof two subscribing witnesses.
